Best Water Cooling Systems of 2025

“This is my first AIO cooler, and I’m pleased with its performance. It keeps my 7900x idling around 33-34 degrees and peaks at 37 degrees during intense tasks. Installation was straightforward, especially on my AMD x670e board.”

“I find the NZXT Kraken 360 feels sturdy and high-quality. My cooling temps are now in the 30s and 40s, and I haven’t had any noise issues so far. Performance is amazing, with temperatures rarely exceeding 40-60 degrees during gaming.”

“I really enjoy the LCD screen that displays my CPU/GPU temps. It's incredibly quiet, making it perfect for gaming or working in a quiet setting. Installation was a breeze, and I’m very happy with this purchase.”

“I love how pretty the cooler looks and it cools my CPU exceptionally well. With my over-clocked setup, it stays at 37°C idle and 40-50°C under load. The Arctic PWM fans are very quiet, and overall, it functions as intended. I did have to unplug and reconnect the RGB plugs for them to work, which was a small inconvenience. But honestly, it’s a solid AIO for the price.”

“I’m really impressed with the chunky radiator and the unique mounting design. It’s almost twice as thick as other brands, so I made sure to check for clearance in my case. The Arctic Silver thermal paste included is great and lasts for several applications. I appreciate that it has a 6-year warranty. If you’re looking for a new AIO, I highly recommend trying this one first.”

“I initially ordered a 240mm AIO, but it didn’t fit well, so I switched to a 360mm cooler. This new cooler has significantly dropped my CPU temperatures by 20-25°C, even under heavy loads. The quality is outstanding, and the German engineering truly shows!”

"I own a 9800x3d, and while the cooler does its job, the accompanying software isn't quite up to par. The thermal paste was dry, so I opted to use my old one instead. Nonetheless, it performs well, and I still rate it 5 stars for recommending this cooler."

"This cooler works wonderfully and looks fantastic. The only downside is the software; it's not very intuitive. It required some experimentation to figure it out, but overall, I highly recommend it as a more affordable option for LCD-screened AIOs."

"I've experienced longer delivery times than usual, but the cooler itself is impressive. It keeps my i9-14900K cool, and the screen is really neat."

"I got lucky with the screw lengths. Installation was straightforward and it looks great, significantly reducing my CPU temps compared to my previous air cooler."

"While the installation was a bit tricky, I love the clean white design and the RGB adds a nice touch. Idle temps are around 30-40°C, and I don't hear the fans at all."

"This cooler is quiet and efficient. I had to work around some cords during installation, but overall, it's a great buy for the quality and price."

"I absolutely love this cooler! It keeps my unlocked 12th gen i9 processor running at a solid 5.2 GHz without any issues. The fans are really quiet, and the pump is practically inaudible. The aesthetic of the cooler block is fantastic, resembling a retro futuristic camera lens. However, I did have some trouble with the lighting effects and the Asus Armoury Crate software—it took quite a bit of tinkering to get everything working right."

"Installing the Ryuo III was easier than I expected! The radiator is thick, so I recommend measuring your case beforehand. The packaging was impressive, showing ASUS's care in presentation. However, I found the mounting screws for the fans a bit short, which led to a crack in one of the fan corners during installation. That was disappointing for a new build!"

"I'm really satisfied with this cooler. It effectively keeps my Intel i9 14900k in the low 30s Celsius, even under heavy load. It's quiet, and overall, it’s another great ASUS product. My only issue is with the bloatware needed to display temperatures—I'd prefer not to have to install all that extra software."

"I decided it was finally time for a new AIO cooler because my old one was just too loud. This cooler is significantly quieter and maintains great temperatures: around 40°C at idle and 50-60°C under load. Overall, it's a fantastic upgrade!"

"I purchased this cooler for my Ryzen 9 7900X3D and it has been amazing! I've never seen temps go over 75°C, even under heavy loads. The fans are quiet, and I appreciate the ability to set fan speeds separately. However, I found the mounting to be a bit tricky."

"Coming from a large air cooler, I opted for this AIO mainly for its look. While my temps have increased slightly, the cooler performs well for its size and is very quiet. I'm really satisfied with its appearance and functionality!"

"I initially noticed my CPU running abnormally hot, even when not gaming. After switching to this cooler, my regular use temperatures dropped 20 degrees, and I could maintain around 60 degrees while gaming. Although there was no manual, the installation was straightforward. I did find the noise level higher than my previous fan, but it’s not distractingly loud."

"This cooler was the perfect fit for my dream gaming PC, effectively managing my 9800X3D. I opted for this model over others because of its slimmer radiator and sleek design. As always, I appreciate Corsair for their reliability; installation was a breeze."

"I purchased this cooler for my Ryzen 7 7900X and it performs superbly while fitting nicely into my all-black theme. It's super quiet and efficient. I highly recommend it to anyone looking for a reliable cooling solution!"

"I installed the ARCTIC Liquid Freezer III 420 A-RGB on my Intel i9-12900K, and the difference was night and day. My CPU temperatures have dropped significantly, even under heavy loads. The triple 140mm fans provide excellent airflow, and it runs quieter than my previous AIO. If you're considering overclocking, this cooler handles thermal management impressively."

"After replacing my motherboard, my Thermalright Le Grand Macho air cooler didn't fit anymore, so I opted for this triple-fan closed-loop cooler. It keeps my i9-9900K 3-5°C cooler during normal workloads and my idle temps are now around ambient. The installation was painless, although mounting the radiator was a bit tricky. Overall, I got it for a great price and I'm satisfied with the performance."

"I upgraded from the Arctic Liquid Freezer II 360 to this 420 model and noticed less noise with similar or even better cooling on my i9-13900K. The radiator is quite wide, so it's important to ensure it fits in the case. Overall, I’m pleased with the upgrade!"

"I highly recommend the iCUE system. It all connects easily in series with other fans, and the software simplifies control. Yes, it’s pricier than alternatives, but it eliminates the hassle of figuring out port connections. As a less experienced builder, I wish I had this for my first build."

"This product arrived well packed in a beautiful Corsair box. I immediately noticed its significant weight and large 360 AIO size. I’m excited to install it in my Fractal Design case for my upcoming CPU upgrade. The setup is straightforward due to the included iCUE Link hub. I have high expectations based on my previous Corsair AIO's performance, which has been very reliable."

"I switched from a top air cooler to this Corsair 360mm RX AIO, and it outperforms my previous setup. My CPU temperatures are about 5°C lower, and the installation was quite simple. I appreciate the tool-less bracket swap for mounting, making it easier than my previous cooler. The RGB customization with iCUE is extensive, and overall, this AIO offers great value for top-tier performance."

"I recently upgraded my PC with Thermaltake fans and they have exceeded my expectations on performance and aesthetics. They keep my system running cool while adding a visually striking element to my setup. The airflow is impressive, and the customizable lighting enhances the ambiance."

"Just got the 280V2, my third AIO from Thermaltake. The great surface area and larger fans keep my 14700k down to 80°C at full load. I’m impressed with the performance, but I’m unsure about the LCD brightness compared to the previous version."

"I purchased this water cooler because my last Thermaltake AIO was amazing, and this one did not disappoint. It’s massive, so I made sure it fit my case. After overclocking my CPU, I’m pleasantly surprised that it stays under 50°C during heavy gaming."
